WINDING APPARATUS Filed July 12, 1941 INVENTORS CYRIL M. CROFT ALVIN W. BERGERON FREDERICK DODGE ATTORNEYS Patented Jan, 12, 1943 UNITED STATES PATENT .OFFICE'V I arouse wmnmc. msas'rus Cyril M. Croft and Alvin W. Bergeron, Cumberlan and Frederick G. signers to Celanese Co corporation of Dclaw Dodge, La Vale, Mi, asrporation of America, a are Application July 12, 1941, Serial No. 402,092 Claims. (01. 242-16) This invention relates to textile apparatus and relates more particularly to a means for winding or batching fabrics on a take-up roll or shell.

When textiles are being processed after weaving and are being dyed or given some other finishing treatment as on a jig or a winch, the

fabrics are normally taken-up or wound on rolls or shells. In this form, the fabrics are easily handled and the compact character of the toilet fabric facilitates the movement of. the fabric from one finishing process to another. One

ing an excessive amount of creasing in the fabric.

In addition, the excessive build up of the selvedge causes a certain amount of stretching along theselvedge which makes the fabric more difficult to ,iandle in finishing operations due to slack selvedges.

It is, therefore, an important object of our invention to provide means in a device for winding fabrics whereby the fabrics may be wound so as to avoid the piling up'of the fabric selvedges.

Another object of our invention is the provision of apparatus for winding fabrics which is simple in operation and durable in construction;

Other objects ofour' invention together with certain details of construction and combination 1 of parts will be more particularly described in the specification and pointed out in the appended claims.

In the drawing:

Figure 1 is a side elevational view showing the path of the moving fabric, the rolls over-which it passes, and the roll upon which it is batched or wound, I

Figure 2 is a view, partly in cross-section, taken along the line 22 in Figure l in the direction of the arrows; and

Figure 3 is a slde-elevational view analogous to the view in Figure 1 and showing, in addition. the means whereby each of the rolls is driven.

Like reference numerals indicate like parts throughout the several views of the drawing.

Referring now to the drawing, and particularly to Figure 1 there is shown a fabric winding device in which a fabric 4, which is to be wound, is passed in the direction indicated by the arrows over a driven guide-roll 5, over a pair of guide-rolls 6 and 1, over a driven guide-roll 8, and is then taken up on a roll or winding shell 9 mounted on a shaft In, thus forming roll of fabric u. R011 I is symmetrically mounted on a shaft l2, while rolls 6 and 'l are symmetrically mounted on shafts- I2 and I4, respectively, and all three rolls rotate in fixed rotational paths. Roll 5, however, is so mounted as to describe an unsymmetrical or eccentric path as shown in Figure 1. To this end, roll I has fixed in the center ofone end; thereof a stub shaft II, and at the otherendv thereof roll 5 is'provided with a stub shaft I8 H which shaft is so mounted as to be slightly offcenter. Shafts II and i0 rotate in suitablebearings l1 whichbearings are mounted in brackets II as by knuckles l a, said brackets being supported by channels which constitute a portion of the frame (not shown) of the winding device. a

By reason of the mounting of bearings II in knuckle Joints i 9, free relative movement between said bearings and brackets it may be obtained thus permitting the unhampered, eccentric, oncenter rotation of roll 5. I

Roll I and roll I are driven by the rotation of shaft ID, the latter being driven by suitable means (not shown) while rolls 6 and I act merely as guide-rolls and are undriven. To drive roll 5 and roll 8, shaft II, as shown in Figure 3, is provided with a grooved pulley 2| fixed thereto. Roll 2 is provided with a grooved pulley 22 mounted on the shaft l2 of said roll and roll 5 is provided with a grooved pulley 22 mounted on the shaft I! of said roll. In addition to pulley 22, shaft l2 has mounted thereon a smaller grooved pulley 24. The rotation of shaft l0 rotates pulley 2| which in turn Pulley 24 on shaft I2 is likewise rotated and this movement is transmitted to pulley 23 through a belt 2', thus causing roll 5 to rotate.

Due to the fact that the diameter of pulley 2| is smaller than that of pulley 22, as shown in Figure 3, roll 8 rotates at a somewhat lower speed than roll 9, and, since pulley 24 is of a smaller diameter than pulley 22, roll 5 is rotated at an even lower speed than roll 8. The result of the progressive increase in speed of the rolls 5. 8 and 9 i is that fabric 4, which'is being wound or batched on roll 8 at a constant speed, is caused to slide over the surface of roll I as roll 5 rotates, since the fabric is moving at a speed greater than the This sliding action likewise occurs when fabric 4 passes over roll I. Since roll I is describing an eccentric ro- 7 be driven from a source of'power independent ofv tailed description by way of illustration. and that many variations may be made therein without departing from the to secure by Letters Patent is:

' ogous to roll 5. caused to describe rolls to be taken up on a bination with a driven take-up operating with said driven at least some ofsaid Y ing means being adapted to drive said driven guide-rolls at a peripheral speed below that of 9 with the selvedges out or register or staggered. Since the position of the selved ge is thus staggel-ed as the fabric is wound, the piling up of the 'selvedges is overcome and, as a result, turned and stretched selvedges are avoided as is excessive creasing of the fabric.

While we have shown the use of belt and pullley means whereby roll and roll 8 may be driven,

j it will be appreciated that these rolls may likewise be driven by gear mechanism or by means ot a chainand sprocket drive; Also, said mils may that employed ior rotating roll 9. While we preferably cause only roll 5 to describe the eccen-' trio rotational motion which imparts the desired side to side motion to the moving fabric. roll 8 may likewise be constructed in a manner anal- In this way both. rolls may be unison or somewhat out'of register, so as to impart a side to side motion of any extent in the 7 fabric being wound.
